Metabolite Identification
Common NameN-Acetylgalactosamine 6-sulfate
DescriptionN-Acetylgalactosamine 6-sulfate is found in keratan sulfate and chondroitin 6-sulfate. PMID: 12489154 . Morquio syndrome is caused by an abnormal accumulation of mucopolysaccharides - in this case, keratan sulfate - in the body. Keratan sulfate is excreted in urine. The symptoms vary from patient to patient, and may include hearing loss, cataracts, skeletal dysplasia, spinal instability, and minor respiratory issues, among others. Two forms are recognized, type A and type B. Type A is a deficiency of the enzyme N-acetylgalactosamine-6-sulfate sulfatase. (Wikipedia).
